A verb appearing in the Lament of Akallabêth in the form ayadda “(it) went” (SD/247, VT24/12). Its initial element is the 3rd persons neuter plural suffix a- “it”. This leaves the basic verb form yadda, which is the past tense according to the theories used here.

Conceptual Development: It appeared in the form yadda in the first draft version of the Lament, and this form was also briefly considered as a replacement for unakkha “he-came” in the first sentence of the Lament (SD/312).
